Zau de Câmpie (Hungarian: Mezőzáh, Hungarian pronunciation:[ˈmɛzøːzaːh]) is a commune in Mureș County, Transylvania, Romania composed of nine villages: Bărboși (Mezőszakál), Botei (Botadűlő), Bujor-Hodaie (Bozsortanya), Ciretea (Bábod), Gaura Sângerului (Szengyelisuvadás), Malea (Boriskadűlő), Ștefăneaca, Tău (Mezőszélen), and Zau de Câmpie.

It lies on the banks of Pârâul de Câmpie (a right tributary of the river Mureș), which forms a string of lakes through the locality.

It borders the following communes: Șăulia and Papiu Ilarian to the east, Valea Largă to the west, Miheșu de Câmpie to the north, and Tăureni to the south.

After the advent of the Romanian People's Republic, Zau de Câmpie became in 1950 part of the Turda raion of Cluj Region.
